'Careless' in the Bible

For the backsliding of the simple will kill them. The careless ease of fools will destroy them.

Rise up, you women who are at ease! Hear my voice! You careless daughters, give ear to my speech!

For days beyond a year you will be troubled, you careless women; for the vintage shall fail. The harvest won't come.

Tremble, you women who are at ease! Be troubled, you careless ones! Strip yourselves, make yourselves naked, and put sackcloth on your waist.

In that day shall messengers go forth from before me in ships to make the careless Ethiopians afraid; and there shall be anguish on them, as in the day of Egypt; for, behold, it comes.
